P PT. Ingress Malindo Ventures is a company which produces several types of door sash for automobiles. The study was conducted in Plant II, which has a 9 machine. The problem that occurs is less perfect engine maintenance system that is used by companies today according to high machine downtime. The stages of the research process, beginning with identifying the critical lines, critical machinery and critical components. Every critical component is calculated replacement time interval of prevention and inspection intervals by calculating the distribution of initial identification, Goodness of testing, and calculate the parameters in order to obtain the value of availability and reliability. Furthermore, the effectiveness values are calculated so that the machine can know the value of Overall Equipment Effectiveness (OEE). The purpose of this study is to determine the critical engine and critical components, calculate and analyze the value of-the initial OEE and recommend treatment with the method of Lean management Total Productive Maintenance (TPM) as well as designing autonomous maintenance roll forming machines. The company currently has OEE of 62.96% in the period February 2014 t s April 2014 for roll orming machines. The results are still far from the optimum value o OEE. OEE is not optimum because the availability factor and low efficiency perfo ce. Based on this analysis, further identification was then performed with e of the Lean Total Productive Maintenance (TPM), Lean Pilot using p Tram to ean Assessment using the Big Picture Mapping (BPM) and Process Activity Mappirig (P r identify the root cause of subsequent problems and recent, Lean Preparation.
